Why San Bruno Residents Choose Us for Medeco Service

Medeco isn’t a brand most locksmiths see every day. It’s a restricted-keyway, sidebar-and-pin-stack system that demands bench discipline – and we work with it constantly. Medeco sales & service is a core part of our shop, not a footnote. Roland grew up in the Excelsior and spent the better part of three decades working San Francisco’s neighborhoods before bringing that same craft down the Peninsula. His bench experience with Medeco’s sidebar systems means we diagnose a binding bolt or a worn pin stack on the first visit, not the third.

We’re based on the Peninsula and serve all of San Bruno service area, from Bayside to Rollingwood. We stock genuine Medeco cylinders and pins locally so a rekey doesn’t wait on a distributor. And we quote the full price on the phone – no add-ons when the tech arrives.

Common Medeco Locksmith Problems We Solve in San Bruno

• The key turns partway and stops. On Medeco Maxum and Original deadbolts, years of key insertion wear the sidebar and pin stack. The key still fits, but the cylinder won’t complete its rotation. We rebuild the cylinder when the body is sound, replacing worn pins and sidebar springs with genuine Medeco parts.
• The deadbolt binds against the strike. San Bruno’s fog season swells 1950s wood doors, and the hardened Medeco bolt then hits a strike plate that has drifted in the original jamb. Owners assume the lock failed. We true the strike, adjust the frame prep, and the bolt throws clean.
• Outdoor entry sets seize up. Salty marine air off the Bay pits exposed brass and steel on Bayside and Crestmoor flats. Thumbturns and deadbolts that were never lubricated get stiff, then immobile. We free them, clean the corrosion, and lubricate with a dry film that holds up in fog.
• The restricted key card is lost at turnover. Landlords near the El Camino/BART corridor often inherit Medeco cylinders with no signed key card. We rekey the cylinder to a fresh restricted key rather than cutting copies from a worn original – no card, no copies, period.
• A “broken lock” that is actually a swollen door. In Crestmoor and Rollingwood, the original mortise locks have worn strike plates. When a fog-damp door swells, it jams against the strike and the lock feels broken. We adjust the strike and lubricate the mortise before recommending any replacement.

Medeco Service in San Bruno: What Local Conditions Mean for Your Equipment

Here’s something we see in San Bruno that a locksmith from Mountain View or San Mateo might not expect. In the older Crestmoor and Rollingwood tracts, the original 1950s mortise locks have strike plates that have drifted over seven decades. The fog keeps humidity constant, and when the wood doors swell, the deadbolt or mortise latch hits a strike that is no longer aligned. A Medeco Maxum owner calls us convinced the high-security cylinder failed – and nine times out of ten, the cylinder is fine. The strike moved. The frame moved. The lock just reports the problem. We true the strike, prep the frame, and only then install or rekey the Medeco. That sequence matters, because bolting a $200 deadbolt into a misaligned jamb guarantees a call-back. Along the BART-adjacent rental corridor, the story flips: turnover is constant, key cards vanish, and landlords need fast, documented rekeys on restricted keyways. That split – vintage doors on one side of San Bruno, fast-turnover units on the other – is exactly the kind of work Medeco hardware demands of a technician, and it’s the work we’re built for.

Medeco Models & Products We Service in San Bruno

We service the full Medeco residential and light-commercial range: the Maxum deadbolt, the M3 and M4 high-security cylinders, the Original Biaxial deadbolt, and the NexGen and eCylinder electronic lines. Where the restricted keyway or high-security rating depends on it, we use genuine Medeco cylinders, pins, and sidebar springs. For door-prep items – strikes, reinforcement plates, frame hardware – quality aftermarket parts do the job without compromising the cylinder. Our honest stance: rebuild a worn Medeco when the body and sidebar are sound, and replace only when the housing is cracked, corroded through, or the restricted keyway can no longer be documented.

FAQs – Medeco Locksmith in San Bruno

My Medeco key turns partway and stops – is the lock failing or is it my door? Both are possible, but in San Bruno the door is usually the culprit. Fog-damp mornings swell 1950s wood doors, and the Medeco bolt then binds against a drifted strike plate. We check the strike first, then the cylinder. If it is the cylinder, worn pins or sidebar springs are the likely cause. Call (833) 589-8078 and we’ll tell you over the phone which one it sounds like.

Can you rekey a Medeco high-security cylinder without the original key card? Yes. The card documents the restricted keyway, but we can rekey the cylinder to a fresh restricted key without it. We cannot cut copies of a restricted key without proper documentation, and we won’t – that’s the whole point of the system. A rekey gives you a new key and a clean key registry.

Will a Medeco deadbolt fit the original mortise prep on my 1950s Crestmoor door? In most cases, no – not without frame prep. The original mortise prep is cut for a different footprint, and the strike plate has likely drifted. We true the strike, prep the frame and bore, then install the Medeco deadbolt so it throws clean in both wet and dry weather. This is the single most common install detail we handle in Crestmoor and Rollingwood.

Why is my outdoor Medeco entry set pitting and getting stiff? San Bruno’s salty marine fog air pits exposed brass and steel over time, especially on the flats near the Bayside side. Stiff thumbturns and seizing deadbolts are corrosion problems, not cylinder failures. We free the hardware, clean the corrosion, and apply a dry-film lubricant that doesn’t attract the salty grit. If the housing is corroded through, we replace it.

I’m a landlord near the El Camino/BART corridor – can you rekey Medeco units between airport-shift turnovers? We do this regularly. Turnover rekeys on restricted Medeco cylinders, documented per unit, with fresh keys handed to you at the door. We work around short vacancy windows because we know an empty unit loses money every day. Call (833) 589-8078 with the unit count and we’ll give you a flat per-lock price and a schedule.
